Euth, Chicago, Ill.. assignor to The United Autographic Register Company, Chicago, Ill., a corporation of Illinois 6 Claims.

In this invention applicant has produced a radical departure from such alignment devices as are usually employed to secure correct alignment of two or more form printed webs such as are used in autographic registers and other devices necessitating the use of two or more webs of stationery one or more of which contains forms which are printed in duplicate, triplicate and the like for, receiving hand or type written records, orders,

sales or other transactions.

An object of the invention is to simplify the operation of and mechanism for obtaining perfectly superposed registration of the forms print-- ed on the two or more webs, so that notations made on the uppermost printed form will appear in identically the same relative position on the remaining superposed forms.

A further object is to produce an alignment mechanism in which longitudinal as well as lateral individual shifting of the superposed formprinted webs forward. backward or to either side is secured either by suitable manipulations upon the webs through the apertures or punched holes therein.

These and other objects are attained in the alignment device described in the following speciflcation and illustrated in the accompanying drawings in which:

Figs. 7 and 8 are details of the simple form of the invention as shown in Figs. 5 and 6.

Figs. 9 and 10 are somewhat diagrammatic views showing the manner in which the elements shown in Figs. 7 and 8 function.

Figs. 11 and 12 are views showing in plan the respective positions and conditions of the superposed webs before and after the aligning operation.

I will first describe the invention as applied to Figs. 1 to 4 inclusive. Here I have a register frame i3 which carries a. drive shaft H upon which a crank i5 is provided for rotation of the shaft. The shaft carries a gear l6 which meshes 5 with a pinion ll mounted upon a transverse shaft i8 located above shaft II. The shaft it carries discs i9 which are notched, while shaft l8 carries smaller feeding discs 20 which rotate in contact with discs i9 tightly enough to grip the form- 10 printed webs between them. This contact permits feeding of the webs forwardly at all such times except as when the notch of disc is is presented to roller 2|). At this time the webs are released for aligning action upon them by the 15 aligning device. Such, in general, constitutes a feeding device which may be employed with my improved aligning device, but to which I do not lay especial claim at this time.

As illustrative of embodiments of my invention, 20 I have shown several forms thereof. The invention to which I lay especial claim is that of causing the alignment of two or more superposed webs by bringing a collapsible pin into engagement with the superposed apertures of the webs and then ex- 25 pending such a pin to adjustable positions of the webs relatively to each other by bringing the apertures into absolute registration. 01 course, it may be understood that the printed forms and the apertures of each web are identical and are 30 identically spaced in each instance, so that registration of the apertures will cause registration of the printed forms.

In the form shown in Figs. 1 to 4 inclusive, the collapsible pin is embodied in two elements 2| and 35 22. The former element is hollow to permit of its movement relatively to the latter element and it may be conveniently provided with a forwardly hooked upper edge 23. The collapsed position of the pin elements is shown in Fig. 2, while the 40 expanded position is shown in Figs. 1, 3 and 4. For the purpose of causing this relative movement, the element 2! is preferably the one with which the pin expansion is created. This may be done by making pin element II as a turned up 45 lug on a reciprocally mounted plate 25 associated in sliding relation to a stationary plate 24 from which pin element 22 is formed. Normally the plate 25 may be held yieldingly in pin contracted position by a spring 26. 50

This position is changed to expanded condition by causing forward movement of the plate 25 against the tension of spring 26. In order to do this I have equipped shaft ll with a cam 21 and plate 25 with a finger 28 cooperating there- 55 with. With this mechanism, rotation of the cam releases the plate 25, and its pin element 2| moves to collapsed condition relatively to element 2!.

The coordination of the discs l9 and cam 21 is such that during rotation of the discs, the cam 21 expands the pins, after the paper webs have been fed forward between the segmental discs I! and rollers 20 and over the pins. At the time the feeding surfaces separate upon presentation of the notches to the rollers, the pins have reached their fully collapsed condition and the webs have been released from feeding movement, the apertures of the webs having permitted them to spring or drop over the pins. With the parts in this condition it is but necessary to rotate the crank until the cam engages the finger 28, thereby causing rapid expansion of the pins within the web apertures. Should there be any misalignment of the webs the positions of the superposed apertures will, by this action, be corrected and perfect alignment thus attained. Operation of the machine is stopped at this point. After such a web feeding and alignment, the projected portions 29 may be torn off over a tearing edge 30, while a knife 3| may be used to cut ofl others of the projected web portions within the register casing. It will be seen that the inclined face 23* of pin element 2| extends upwardly from its rear to its front hooked edge 23. This formation is to enable the pin to be self stripping. By this I mean that when the .pin has been placed in collapsed condition, the subsequent feeding movement of the paper webs will cause them to lift up and pass over the pins automatically without' having previously been lifted therefrom.

In Figs. 5 to 12 inclusive, a somewhat different form of the invention is shown. In this form the device is simple because it is primarily intended for memoranda. or similar purposes, in which it is desirable to have one or more copies of the memorandum made from the original simultaneously with its writing. A simple framework 32 provides rotatable support for a multiple wound roll of stationery 33 which may furnish the paper supply for the flat writing portion ll of the device. A tearing knife 35 at the forward edge of the device, is provided to permit the used portions of the web to be torn off. This knife has holes 36 through it in registration with aligning pins extending through the holes. These pins are of the split type, in which the two half pins 38 and 39 are capable of being brought together and separated to secure alignment of the webs. The halves 38 of the pins are located on one bar 40 while the other halves 39 of the pins are located on another bar I l These bars are normally separable under tension of springs 42 and 43 for bringing the web forms into registration, while they may be drawn together to permit the web apertures to be placed over them. At the ends of the bars 40 and 4| are the half trunnions 44 and 45 which govern the bringing together of the pin-bearing bars. To accomplish this bar movement, the tearing knife 35 is provided with arms l6 which are secured to a shaft 41 to which a lever 48 is secured for raising of the knife, springs 9 being provided for clamping the knife upon the webs. The 48 are slotted just beneath the knife to provide an enlarged upper slot end 50 and a constricted lower slot end 5|.

When the knife is raised the trunnion halves 44 and 45 are drawn together thus bringing the aligning pins to collapsed condition. This permits the webs to be drawn out and placed with their apertures over the pins. Then the knife is lowered and in doing so the trunnion halves M and 45 are allowed to enter the wider portions 50 of the slots in the side arms 46. The springs 32 and 43 are then permitted to function in draw- 5 ing the bars and consequently the pin halves I8 and 38 apart. This occurring within the aligning apertures of the webs causes movement of the misaligned webs from the condition shown in Fig. 11 to that shown in Fig. 12 in which perfect in alignment has been established.

A feature has been shown in Fig. 3, to which I draw attention. This consists of aseries of vanes, blades, slats or shutters 52, i3 and 54 over which the webs are drawn. These slats are mounted 15 pivotally between the sides of the register so that they may rest upon the webs and exert friction upon the webs as they are drawn from the source of supply, thus holding them more tautly upon the register platen and thereby avoiding wrinkles 20 and air pockets between the webs by the application of tension. Of course in the making of copies the usual interleaved carbon paper is used for this purpose, and it is equally obvious that other means than that of the specific slats 25 disclosed may be employed to perform the same function.

As appears from Figs. 3 and 4, the pin-members 2| and 22 are supported at their lower ends and have free upper ends over which the strips, drawn 30 from a source of supply (shown as a roll), pass, until a set of register-perforations drop over the free ends of the pins, whereupon the pin-members are given a relative movement longitudinally of the strips to bring the forms into registration. 35 This feature, in a duplicating machine, provides corrective action, insuring correct superimposed relation of the forms before the forms are inscribed.

I disclaim from the scope of the claims all con- 40 structions excepting those in which the pin-element is supported at one end and presents a free end to the web, adapted to enter the web-apertures, in turn, as they arrive thereat.

Having thus described my invention, what I 45 claim is:
